Gravestone maintenance involves the care and preservation of headstones and memorials in cemeteries. This includes cleaning the stone to remove dirt, moss, and lichen, which can cause damage over time. Regular inspections help identify any cracks or structural issues that may need repair. Additionally, gravestone maintenance may involve resetting stones that have become uneven or unstable. It is important to use appropriate cleaning materials to avoid damaging the stone. Many cemeteries offer maintenance services, or families can hire professionals who specialize in the care of gravestones and memorials.
